BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a radiator structure and particularly to a radiator structure combining different metals.

2. Brief Description of the Related Art

Due to high technology developing progressively and prosperously, the electronic component such as CPU is made to approach miniaturization with higher intensity per unit area and reinforced performance. Under these factors, gross heat generation of the electronic component is getting more than ever before. Thus, in case of no good cooling way being introduced for removing the heat, excessively high temperature results in the electronic component occurring phenomenon such as thermal runaway and thermal stress to lower integral steadiness thereof and shorten the life span thereof. Hence, how to dissipate high temperature heat created by the electronic component and avoid overheated electronic component with the aid of external cooling device/system is a problem indispensable ignorance.

Generally, there are four cooling ways, which are frequently seen, are 1. forced-air cooling; 2. natural cooling; 3. phase change cooling and 4. liquid cooling directly or indirectly. Mostly, the forced-air cooling in association with a radiator is popularly used for achieving cooling effect. The radiator provides fins to assist the electronic components dissipating heat because the fins increases heat dissipation area of the electronic component. Further, fin type air-cooling radiator adopts air as the working medium, which is easy to be acquired and steady and it is won't hurt the electronic component. In addition, the radiator basically is made of aluminum and copper with low cost and high heat dissipation coefficient. Moreover, aluminum and copper are easy to be worked so that the radiator being incorporated with design of geometry and optimum is favorable for solving heat dissipation problem of the electronic component.

Conventionally, the radiator is made of extruded aluminum but aluminum provides poor conductivity in spite of fast heat dissipation. Under this circumstance, the high temperature heat from the electronic component is unable to transmit via the aluminum made radiator rapidly so that it is ineffectively for the conventional radiator to dissipate heat actually. As for copper made radiator, better heat conductivity can be obtained but poorer heat dissipation rate is provided than the aluminum made radiator. Further, the copper made radiator needs higher production and it leads to high overall cost and selling price so that it is hard to be accepted by users.

Thus, in order to combine properties of fast heat dissipation offered by aluminum and fast heat conduction offered by copper, a radiator with aluminum and copper is fabricated as shown in FIG. 1, that is, an aluminum part 11 and a copper part 12 are provided to be closely adjacent to each other. The aluminum part 11 has several fins 13 extending outward and the copper part 12 is closely contacting with the electronic component 14 so that heat from the electronic component 14 can be transmit rapidly by the copper part 12 and removed outward via the aluminum part 11 and the fins 13.

Alternatively, an aluminum part 21 and a copper part 22 are provided as shown in FIG. 2 and the aluminum part 1 has a recess 211 at the middle thereof for receiving the copper part 22, which has the same shape and size as the recess 211. The aluminum part 21 has several fins 23 extending outward. The copper part 22 closely contacts the electronic component 24 so that heat from the electronic component 24 can be transmitted via the copper part 22 to the aluminum part 21 and the fins 23 so as to dissipate the heat rapidly.

Referring to FIGS. 3 and 4, an aluminum part 31 is hollow post with a through hole 311 and a plurality of fins 33 extending radially from the circumferential side thereof. A copper part 32 tightly fits with the through hole 311 to allow the lower end of the copper part 32 closely contacting an electronic component 34. The heat from the electronic component 34 can be transmitted via the copper part 32 to the aluminum part 31 and the fins 33 so as to dissipate the heat rapidly.

However, a common problem in the preceding three conventional radiators, which combine different materials, while the conventional radiators are implemented is in that the copper part 12, 22, 23 centralizes at a preset zone and heat aggregates at the copper part 11, 21, 31 and a little section of the aluminum part 12, 22, 32 adjacent to the copper part 11, 21, 31 such that heat is incapable of distributing to the fins 13, 23, 33 effectively. In other words, the conducted heat is unable to distribute evenly to the entire radiator and it is not possible to enhance the heat dissipation effect.

Moreover, the aluminum part 11, 21, 31 and the copper part 12, 22, 32 are different in weight and the aluminum part 11, 21, 31 is easy to become separate from the copper part 12, 22, 32 such that it results in the radiator provides shortened life span.

Another object of the present invention is to provide a radiator structure in which the conductive component is placed in the base and the fins in a way of being arranged as strips or a sheet or a net to increase cooling area and conduct heat evenly and rapid heat removal.

Accordingly, a radiator structure according to the present invention includes a base and at least a conductive component. Several fins extend from the base and the conductive component is associated with the base and the fins. The conductive component is locally located at the base and the fins.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 5 and 6, the preferred embodiment of a radiator structure according to the present invention includes a base 41 with a plurality of extending out fins 411 and at least a conductive component 42. The conductive component 42 is joined to the base 41 and the fins 411. Preferably, the conductive component 42 is joined to interiors and/or surfaces of the base 41 and the fins 411 in a way of partly mounted to, fitting with or embedded in on the base 41 or the fins 411. That is, the conductive component 42 is located at all both the base 41 and the fins 411. Preferably, the conductive component 42 being partly mounted to the base 41 and the fins 411 is arranged with members of the conductive component 42 spacing apart to each other in a way of being in parallel, non-parallel or intersecting. The conductive component 42 is formed with a material different from the base 41 and the fins 42, i.e., the base 41 and the fins 411 are made of a first metal and the conductive component 42 is made of a second metal, which is different from the first metal.

The conductive component 42 can be formed with a shape of sheet as shown in FIG. 7, a plurality of parallel lines as shown in FIG. 8, a net as shown in FIG. 9, a plurality of grains as shown in FIGS. 10, 11, a honeycomb as shown in FIG. 12, a point matrix as shown in FIGS. 13 and 14, radiation as shown in FIG. 15, spiral as shown in FIGS. 16 and 17, concentric circles as shown in FIG. 18, a cobweb as shown in FIG. 19 or irregular geometry (not shown). Further, conductivity efficiency of the second metal is higher than the first metal. For example 1, in case of the first metal material being aluminum, the second metal material is gold, silver or copper or a conductive material with a coefficient of conductivity better than the first metal material. For example 2: in case of the first metal material being copper, the second metal material is gold or silver. The first metal material and the second metal material are not limited the preceding material and other materials can be used.

When the base 41 is closely attached to an electronic component 43, most of heat generated by the electronic component 43 is conducted rapidly with the conductive component 42 and rest of the heat is conducted via the base 41 and the fins 411. The heat conducted by the conductive component 42 can be transmitted with the base 41 and the fins 411 too. That is, all the heat can be conducted to the entire radiator and the heat can be removed rapidly with the base 41 and the fins 411. Further, an external device such as fan (not shown) occurs forcing convection to constitute a feature of exchange between cold air and the fins 411 and the conductive component 42 so as to remove the heat and enhance heat dissipation efficiency largely. Due to the conductive component 42 providing the size thereof distributing in the interior and/or the surface of the base 41 and the fins 411, feature of increasing the heat dissipation efficiency can be obtained as long as the base 41 and fins 411 have heat conduction and heat dissipation area, i.e., area contacting with the air being increased. In this way, deficiency of the prior art that conducted heat is congregated at the copper material and it results in heat is distributed inconsistently and incapable of transmitting to aluminum material can be overcome.
